Shiritsu Ebisu Chuugaku members Mayama Rika and Nakayama Riko have tested positive for COVID-19. 

According to the group's official website, Mayama had a fever on March 20th, so she conducted the PCR test and was confirmed positive for the virus. Meanwhile, Nakayama conducted the PCR test after breaking out with a fever when she was also diagnosed with the virus. While the other members do not have any symptoms, it is likely that they are close contacts, so they have all been tested as well and are isolating at home until they receive their results. 

Consequently, Ebichu's album release event that was scheduled from the 21st to the 25th have been postponed. More details will be announced later.
